// .NAME vtkCompositer - Super class for composite algorthms.
|
|
//
|
|
// .SECTION Description
|
|
// vtkCompositer operates in multiple processes. Each compositer has
|
|
// a render window. They use vtkMultiProcessControllers to communicate
|
|
// the color and depth buffer to process 0's render window.
|
|
// It will not handle transparency well.
|
